  • Its Crystal Structure and Relationship to A-Pbf2
    American Mineralogist, Volume 81, pages 1277-1281, 1996 Laurelite: Its crystal structure and relationship to a-PbF2 STEFANO MERLINO,! MARCO PASERO,! NATALE PERCHIAZZI,! AND ANrHONY R. KAMPF2 lDipartimento di Scienze della Terra, UniversitA di Pisa, via S. Maria 53, 1-56126 Pisa, Italy 2Mineralogy Section, Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, U.S.A. ABSTRACT Laurelite, Pb7F12CI2, from the Grand Reefmine, Graham County, Arizona, is hexagonal, Po, with a = 10.267(1) and c = 3.9844(4) A and Z = 1. The crystal structure was solved by direct methods and refined to R = 0.035 and RW2= 0.089 for 693 measured reflections (Fo > 9O'Fo)' The structure is related to that of a-PbF2. Both are based upon ninefold-coordinated Pb as tricapped trigonal prisms (TCTPs), which share edges and faces. The two structures can be described with respect to the face-sharing linkages of their TCTPs. The structure of a-PbF2 consists of corrugated sheets of face-sharing TCTPs that interlock by edge-sharing perpendicular to the c axis. In laurelite, the Pb2 TCTPs form three-membered face-sharing clusters about the threefold axis that are propagated into trigonal cylinders by sharing faces in the direction of the c axis. The Pb 1 and Pb3 TCTPs are linked by face-sharing into a three-dimensional framework with corresponding cylindrical voids. Asymmetric coordi- nations about Pbl and Pb2 are attributed to the stereoactive lone-pair effect. Although the coordinations about the anions appear to disallow substitution of OH for F, stacking defects along the c axis provide a mechanism for accommodating limited OH or H20 for F substitution.

  • A Specific Gravity Index for Minerats
    A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951).

    WHERRYITE, A NEW MINERAL FROM THE MAMMOTH MINE, ARIZONAT Richf'eld, Josern J. Fannv, tI . S. GeologicalSurvey; E. B. Dacortr, [Jtah; lNo S.cMunr.G. Gonnow, The Academy oJ l{atural Sciences oJ PhiladelPhia. Aesrnacl A new mineral from the Mammoth Mine, Arizona, having the formula Pbcos'2Pbsor .Pb(cl, oH)z.cuo is named in honor of Dr. Edgar Theodore wherry. The indices of re- fraction are a:1.942, P:2.01O and 1:2.924, and 2V:50' (calculated)' The specific gravity is 6.45. Wherryite was found in a vug just above the 760-foot level associated with chrysocolla, diabol6ite, and paralaurionite' IurnolucrroN In May of 1943 one of the authors, E. B. Daggett, then mining en- gineer at the Mammoth Mine, discovered a small vug of leadhillite crystals associatedwith cerussite, anglesite, phosgenite, paralaurionite, hydrocerussite, diabol6ite, bol6ite, matlockite' and quartz. Within the cavity was some friable chalcocite with a relict structure of the galena which it has replaced. The massive wall of the vug consisted ol a light-green fine granular mineral enclosing some bluish chrysocolla, and at the cavity some blue diabol6ite and greenishparalaurionite. This green matrix was up to five cm. in thickness and extended to the silicified wall of the vein-an altered qrartz monzonite. The minerals of this remarkable vug, and the crystallography of the leadhillite will be d.escribedin a later paper; some observations on the paragenesiswill be given here in order to describe the occurrenceoi the green matrix which has proven to be a new mineral. The name wherryite is given to this new mineral in honor of Dr' Edgar Theodore wherry, first editor of the American Minerologist, formerly curator of mineralogy at the U.

Khlopin Radium Institute, Roentgen Street 1, 197101 St Petersburg, Russia *E-mail: [email protected] OCCURRENCE The mineral occurs in the Torr Works (Merehead) Quarry, East Cranmore, Somerset, UK. Yeomanite is associated with mendipite, as a cavity filling in manganese oxide pods. Other oxyhalide minerals that are found hosted in mendipite include diaboleite, chloroxiphite and paralaurionite. Secondary Pb and Cu minerals, including mimetite, wulfenite, cerussite, hydrocerussite, malachite, and crednerite also occur in the same environment. Gangue minerals associated with mineralised manganese pods include aragonite, calcite and barite. Undifferentiated pod-forming Mn oxides are typically a mixture of manganite and pyrolusite, associated with Fe oxyhydroxides such as goethite (Turner, 2006).

  • (2016): Formation and Significance of Laurionite in Geothermal Brine

It was found to precipitate from saline fluids predominantly as laurionite 18 (PbOHCl) forming one of the most dominant scaling minerals identified at the geothermal site 19 Groß Schönebeck (Germany). In this study, its formation conditions and relevance for the 20 environment are investigated and discussed. To simulate laurionite precipitation, various 21 amounts of base (NaOH) were added to solutions containing 3 M NaCl, 1 M CaCl2, and 10 mM 22 Pb(NO3)2 at 25 °C, 80 °C, and 133 °C. The formed precipitates were analyzed by X‐ray 23 diffraction and scanning electron microscopy. In nearly all experiments laurionite had formed 24 as the predominant/ only mineral. Experimental results showed the same trends for 25 equilibrium calculations performed with the code PhreeqC and the database “geodat”. The 26 results indicate that the formation of laurionite from geothermal, Pb‐bearing saline brine is 27 very probable, with the pH value as the main controlling parameter for its formation.

  • (New Species) Paralaurionite. ][. LAURIONITE
    102 On some lead minerals from Laurium, namely, Laurionite, Phosgenite, Fiedlerite, and (new species) Paralaurionite. By G. F. HERBERT SMITH, B.A., With Chemical Analysis by G. T. PRIOR, IVI.A., F.G.S., Assistants in the Mineral Department of the British Museum. [Read April 5th, 1898.] N this paper are embodied the results of an examination of the speci- I mens of lead slags from Laurium in the British Museum. On some of the specimens a new mineral, paralaurionite, was found, which possesses the same chemical composition as laurionite, but entirely different morphological and optical characters. In addition to crystals of the four minerals given in the title, a few crystals oi matloekite and anglesite were noticed, and on one specimen there is a radiating group of prismatic crystals of penfieldite. ][.

Khlopin Radium Institute, Roentgen Street 1, 197101 St Petersburg, Russia *E-mail: [email protected] OCCURRENCE The mineral occurs in the Torr Works (Merehead) Quarry, East Cranmore, Somerset, UK. Yeomanite is associated with mendipite, as a cavity filling in manganese oxide pods. Other oxyhalide minerals that are found hosted in mendipite include diaboleite, chloroxiphite and paralaurionite. Secondary Pb and Cu minerals, including mimetite, wulfenite, cerussite, hydrocerussite, malachite, and crednerite also occur in the same environment. Gangue minerals associated with mineralised manganese pods include aragonite, calcite and barite. Undifferentiated pod-forming Mn oxides are typically a mixture of manganite and pyrolusite, associated with Fe oxyhydroxides such as goethite (Turner, 2006).
